I discovered these silicone portion cubes for the freezer from some friends on a Discord for people with Chronic illnesses and issues. I gotta say, I'm loving this. I've yet to try the other things like veggies, gravies, even pasta that they showed me, but my first two forays are awesome. (more info and links in comments)
Example: 2 of those cubes of sauce are a portion the way I like it. The two jars filled two trays and has enough left over for my lunch or dinner, so that's really 7 portions, or 7 meals. (or me, then 3 meals for me and the person I live with. Still not bad at all.) Links to where I bought them at the end, I'm not an affiliate so I don't get anything for recommending things. Also not why I do it.)
